PHP Warning: array_merge() …

Update, still getting multiple PHP Warnings a day, but the line number has shifted. Now it says
[11-Aug-2022 05:47:15 UTC] PHP Warning: array_merge(): Expected parameter 1 to be an array, string given in /home/customer/www/evangelist.global/public_html/wp-content/plugins/seriously-simple-podcasting/php/classes/controllers/class-frontend-controller.php on line 690

It would appear this line
$tag_archive_post_types = apply_filters( 'ssp_tag_archive_post_types', array( 'post', SSP_CPT_PODCAST ) );
is returning not an array.

Hello @askpivot!

Did you ask someone for any plugin customization?
It looks like somewhere in your code the filter ‘ssp_tag_archive_post_types’ is misused, and returns a string instead of the array.

Please try to look for something like add_filter('ssp_tag_archive_post_types'..." in your code.

Also, disabling any warnings on your production sites is always a good idea. To do it, please check your wp-config.php file, and make sure that WP_DEBUG is disabled:

define( 'WP_DEBUG', false );

Best regards,

Sergiy, development team.

@askpivot

Anyway, thank you for bringing it to our attention. I’m going to add some additional checks there to prevent such warnings in the future.

Okay, I do not see any calls anywhere in our code that apply to the filter ‘ssp_tag_archive_post_types’.

These notices are in our error logs, not public facing.

Thank you! Hoping those safeguards you add remove this notice for us. ??

Marking resolved.

@askpivot

Yes, we resolved it in our recent plugin release. Thank you for your feedback and enjoy the plugin!
